Explain Thomson Model of Atom
J. J. Thomson, in 1898, proposed that an atom possesses a spherical shape (radius approximately 10-10 m) in which the positive charge is uniformly distributed.…

What is Charge to Mass Ratio of Electron
In 1897, British physicist J.J. Thomson measured the ratio of electrical charge (e) to the mass of electron (me) by using cathode ray tube and…
How to calculate Mole Fraction?
Mole Fraction is the ratio of number of moles of a particular component to the total number of moles of the solution. If a substance ‘A’…
What is Suspension?
Suspension is a heterogeneous mixture of solid particles in liquid where the size of the particle is larger than 1 μm. That is why, panicles…
What is Coagulation?
Coagulation is such a process what colloid particles present in a solution are separated coagulant in the solution. This process is used in the industry…
Are the Suspension and Emulsion Same?
Suspension and emulsion is not the same thing. The suspension is the mixture of solid-liquid and emulsion is the similar mixture of liquid Mg(OH)2 mixed…
What is Hardy Schulze Rule?
Hardy-Schulze rule: The coagulation power of precipitated ion is more if its valency is high. For example, coagulation power series of Al3+, Na+ and Ba2+…
